The pots for Apathy and Torpor do not specifically alter the
frequencies, rather the weight of the outputs. Various settings will cause the
signals to spend more time travelling around one strange attractor rather than
the other.

Apathy and Torpor also have CV inputs. Sometimes the CV
signals are injected onto the chaotic signals but depending upon conditions may
cause windows of periodicity or voltage jumps. Generally the results are good.

The X, Y & Z outputs for each Sloth are taken from
different stages of the circuit and are all different to each other, although Z is simply
the inverted version of Y. The three Z outputs are also fed into a Difference
Rectifier and the results of this are available from the + and – outputs at the
bottom of the panel. The Difference Rectifier outputs are (ignoring diode
voltage drops):

out + = VApathy
+VInertia - VTorporIf greater than 0, otherwise 0

out - = VApathy
+VInertia - VTorporIf less than 0, otherwise 0

PCB set (2) - US$24

Aluminium Panel - US$20

assembled - US$210

This is not a suitable build for beginners, if you are new to synth DIY, I suggest you get the thru-hole single Sloth.
